Facebrick is only a necessity for attention whores, stalkers, pedophiles, and the insecure. Social networking is a fad, people. Just like pet rocks. Get over yourselves.
Downvote all you like. Don't care. Those with two brain cells to rub together will look back in five to ten years and try to remember why they thought Fartbook -- and the whole damned "social networking" phenominon -- was such a big deal.
For those that aren't old enough to remember how many times we've been through this cycle, do the research on MySpace, AOL... hell, the list is endless. Google "predecessors to Facebook", learn something about what's gone before, and for Christ's sake, get a life.
